Trait FromJSValConvertibleRc 

pub trait FromJSValConvertibleRc: Sized {
    // Required method
    unsafe fn from_jsval(
        cx: *mut JSContext,
        val: HandleValue<'_>,
    ) -> Result<ConversionResult<Rc<Self>>, ()>;

    // Provided method
    fn safe_from_jsval(
        cx: &mut JSContext,
        val: HandleValue<'_>,
    ) -> Result<ConversionResult<Rc<Self>>, ()> { ... }
}

A trait to convert JSVals to Rust types inside of Rc wrappers.

Required Methods

unsafe fn from_jsval( cx: *mut JSContext, val: HandleValue<'_>, ) -> Result<ConversionResult<Rc<Self>>, ()>

Convert val to type Self. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

Provided Methods

fn safe_from_jsval( cx: &mut JSContext, val: HandleValue<'_>, ) -> Result<ConversionResult<Rc<Self>>, ()>

Convert val to type Self. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
